Washington is the capital of the United States, a city of monuments, museums, and neighborhoods built around public life. The National Mall stretches from the Capitol to the Lincoln Memorial with monuments and the Washington Monument in between, the Smithsonian museums offer free admission to collections covering American history, air and space, natural history, and art, and the White House stands on Pennsylvania Avenue as the home of the president. Georgetown preserves Federal era homes and a historic waterfront, Dupont Circle gathers embassies and bookshops, and Adams Morgan mixes restaurants and music venues.
